• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky ((nang xa) OR (lang ha)) hoi. hieu ((ve cau) OR (ke cau)) duc va hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: te cac ky ((nang xa) or (lang ha)) hoi. hieu ((ve cau) or (ke cau)) duc va hanh vi cuu tre*.
